120AH 12V LiFePO4 series connection capable battery

Crafted out of Lithium Iron Phosphate (LiFePO4) technology, this 120AH 12V LiFePO4 series connection capable battery built to last. With 2,000+ recharge cycles (and up to 7,000 under ideal charging conditions) the 120 Ah provides 5 X the lifespan than your typical SLA battery. Combine 2 for 24 Volts or 4 for a 48 Volt system. ideal for industrial purposes where you need a long lifespan battery that charges quickly, or for outdoor uses like hiking or camping where weight is at a premium.

Battery Management Systems – BMS

A Battery Management System (BMS) is an intelligent component of a battery pack responsible for advanced monitoring and management. It is the brain behind the battery and plays a critical role in its levels of safety, performance, charge rates, and longevity.

Our BMS is designed to be a long-term solution for our customers with the highest level of safety in mind. Advanced algorithms and electronics ensure high precision measurements:

Functionally safe
Fast and efficient balancing
Shortened charging time
Improved range per charge
Maximum battery life

120AH 12V LiFePO4 Series Battery Grade A Cells

Grade A cell is the name of the battery’s high-quality standard. Grade A LiFePO4 battery cells are within the range of technical parameters in all aspects of the parameters, the appearance is intact(no damage), no swelling, amd no abnormal battery can be called grade A.

There are Grade A, Grade B, and Grade C types of battery cells. A manufacturer will rate the cells they produce so as to categorize the performance differences …

Batteries In Series And Parallel

The main difference in wiring batteries in series vs. parallel is the impact on the output voltage and the capacity of the battery system. Batteries wired in series will have their voltages added together. Batteries wired in parallel will have their capacities (measured in amp-hours) added together.

Features

The voltage can be expanded from 12V to 48V to power various products.
Support 4units in series connection, or 10units in parallel connection.
LCD display optional, real-time understanding of battery voltage and capacity.
100A continuous output voltage can continuously charge big-power devices.
The intelligent BMS system can accurately control the battery to improve the lifespan, no explosion, no fire.
Drop-in replacement for heavy lead-acid(AGM / GEL) battery，1/3weight but same capacity.
2000times cycle life@100% DOD , 7000times cycle life@50% DOD , 10 years design lifespan.
Maintenance-free, fully sealed, and waterproof.
